(first embodiment)
The stereogram of first embodiment's a flow dontroller S1 is presented among Fig. 1, and its sectional view is presented among Fig. 2.
As shown in Figure 1, flow dontroller S1 comprises a cylinder-shaped body 2 and a cylindrical adjusting knob 4, and this adjusting knob 4 and main body 2 are arranged also the part of main body covered 2 outer peripheral surface coaxially.One user can rotate adjusting knob 4 with respect to main body 2.
One first port 6a is formed in the one first nipple member 6, and one second port 8a is formed in the one second nipple member 8, and the first nipple member 6 and the second nipple member 8 are attached in the two ends of main body 2 respectively.As shown in Figure 2, fluid passage P1 and P2 (for example, flexible pipe) introduce fluid main body 2 and discharge fluid from main bodys 2, and path P1 and P2 are connected respectively to port 6a and port 8a.
Through hole 2c and 2d relatively are formed in the outer wall of main body 2, and this has constituted the first flow path 2a (seeing Fig. 2 and 3).
As shown in Figure 2, the outer peripheral surface that comprises through hole 2c and 2d of adjusting knob 4 main body covered 2.
One cover 2e is formed in the end of main body 2.An end 4b of adjusting knob 4 is inserted in the cover 2e.Promptly, the one Outer cylindrical part (cover 2e) of separating with the outer peripheral surface of main body 2 is formed in the end of main body 2, and an end 4b of adjusting knob 4 is inserted in the space between the outer peripheral surface of the inner peripheral surface of this Outer cylindrical part (cover 2e) and main body 2.
The first nipple member 6 is fitted in the other end of main body 2.The first nipple member 6 also has a flange portion 6b, and this flange portion radially stretches out along the other end of main body 2, adjusting knob 4 can be remained in the main body 2.That is, adjusting knob 4 is clamped between cover 2e and the flange portion 6b, so that adjusting knob 4 can remain on the outer peripheral surface of main body 2.
A plurality ofly be recessed to form in the inner face 2f of cover 2e (see figure 2) and along the circumferential direction arrange.Can be formed on adjusting knob 4 (see figure 4) on the end face that caves in these depressions protuberance 4c that engage.When the user rotated adjusting knob 4, protuberance 4c moved on depression.On the other hand, when the user when an optional rotational position stops operating adjusting knob 4, protuberance 4c with the depression engage so that adjusting knob 4 can remain on this position.
One first helical thread portion 4a is formed on the part of inner peripheral surface of adjusting knob 4, and it is corresponding to through hole 2c and 2d.That is, the first helical thread portion 4a of adjusting knob 4 is towards the first flow path 2a of the main body 2 of passing through through hole 2c and 2d.
One lobe 2g is formed on the inner peripheral surface of main body 2 and is arranged between flow path 2a and the 2b.A plurality of through hole 2h form the 4th flow path in lobe 2g, they are along the circumferential direction arranged.
One rubber component 10 is attached to the lobe 2g of main body 2, and it is arranged between the first flow path 2a and the second flow path 2b.In rubber component 10, be formed with a lip ring 10a and a valve body 10b, the former seals the first flow path 2a and the second flow path 2b, and the latter forms a taper, extend towards the second flow path 2b from lip ring 10a, and can close the end (seeing Fig. 2 and 5) of the 4th flow path 2h.
As shown in Figure 2, mitre velve body 10b leans outward from the inside of lip ring 10a and tiltedly extends.Because this structure, a neck 10c is formed between lip ring 10a and the valve body 10b.
The surperficial 2i of lobe 2g on the second flow path 2b side forms a conical surface along the moon of the outer peripheral surface of the mitre velve body 10b of rubber component 10.On the other hand, the surperficial 2j of lobe 2g on the first flow path 2a side forms a vertical surface.
The outer peripheral surface of the mitre velve body 10b of rubber component 10 is arranged along ramped surfaces 2i, and lobe 2g engages with neck 10c, so that rubber component 10 remains in the main body 2.
When the hydrodynamic pressure in the first flow path 2a and the 4th flow path 2h is higher than hydrodynamic pressure in the second flow path 2b, because the hydrodynamic pressure in the 4th flow path 2h, valve body 10b pressurized and distortion, like this, fluid flows to the second flow path 2b by the 4th flow path 2h from the first flow path 2a.
On the other hand, during hydrodynamic pressure in the hydrodynamic pressure in the second flow path 2b is higher than the first flow path 2a and the 4th flow path 2h, because the hydrodynamic pressure in the second flow path 2b, valve body 10b pressurized, but valve body 10b is forced into the described end that ramped surfaces 2i went up and closed the 4th flow path 2h.Therefore, fluid can not flow to the first flow path 2a from the second flow path 2b.
That is, valve body 10b plays the effect of a safety check, and it stops fluid to flow to the first flow path 2a by the 4th flow path 2h from the second flow path 2b, and allows fluid to flow to the second flow path 2b by the 4th flow path 2h from the first flow path 2a.
The flow control member 12 of one rod is arranged in the main body 2.Flow control member 12 closely passes lip ring 10a and can move vertically with respect to lip ring 10a.
The notch of one bifurcated (open part) is formed in the described end 12a.The notch opening of bifurcated forms a V-shaped groove mouth on the described end face 12a of flow control member 12 and outer peripheral surface.By forming (V-arrangement) notch of bifurcated, a described end 12a of flow control member forms a V-arrangement (seeing Fig. 2 and 6).The 3rd flow path 12b is played in space in the V-arrangement.
Shown in Fig. 2 and 6, the width of the 3rd flow path 12b or V-shaped groove mouth (open part) little by little increases towards a described end 12a.That is, the width of the 3rd flow path 12b of the circumferencial direction of longshore current amount control member 12 little by little increases towards an end 12a, and little by little increases towards an end 12a perpendicular to the sectional area of the 3rd flow path 12b of the axis of flow control member 12.
In state as shown in Figure 2, a described end 12a of flow control member 12 is corresponding to lip ring 10a.By being moved to the left flow control member 12, corresponding to the sectional area of the 3rd flow path 12b of lip ring 10a with on the first flow path 2a side of opening area at relative lip ring 10a of the opening end of the 3rd flow path 12b of the side of flow control member 12 12c and 12d upper shed, all little by little reduce.Therefore, the fluid flow that flows in the 3rd flow path 12b reduces.More precisely, the sectional area of the 3rd flow path 12b in the lip ring 10a annular portion, and, on respect to the first flow path 2a side of lip ring 10a, suppress the fluid flow that flows in the 3rd flow path 12b in the smaller opening part of the opening end of the 3rd flow path 12b of the side of flow control member 12 12c and 12d upper shed.
That is, the fluid flow that flows in the 3rd flow path 12b can be adjusted with respect to the axial position of lip ring 10a according to flow control member 12.
The V-shaped groove mouth leaves a described end 12a on flow control member 12 bi-side 12c and 12d depth of rebate differs from one another.As shown in Figure 2, the depth of rebate in the front surface 12c is deeper than the depth of rebate in the 12d of rear surface.
Utilize this structure, move when flow control member 12 and a component of V-shaped groove mouth is positioned in the lip ring 10a when reducing the 3rd flow path 12b inner fluid flow, component in the 12d of rear surface is closed by lip ring 10a, like this, the first flow path 2a and the second flow path 2b are not communicated with each other; The first flow path 2a and the second flow path 2b only communicate with each other by the component in the front surface 12c.That is, the first flow path 2a and the second flow path 2b only can communicate with each other by the V-shaped groove mouth in the front surface 12c, and like this, even flow is very little, the fluid flow that flows in the 3rd flow path 12b also can accurately be controlled.
Next, will explain a mechanism of axially mobile flow control member 12, it comprises operation equipment, for example, and adjusting knob 4.
As shown in Figure 2, projection 12g is formed in the other end 12e of flow control member 12, and it is positioned at the first flow path 2a.Projection 12g has the second helical thread portion 12f respectively, each second helical thread portion radially extends with respect to the axis of flow control member 12, till the inner peripheral surface of through hole 2c that passes main body 2 and 2d arrival adjusting knob 4, and the first helical thread portion 4a of each second helical thread portion 12f and adjusting knob 4 screws.
Each projection 12g is made up of the 12ga of a first portion (see figure 6) and a second portion 12gb (see figure 7), the former and flow control member 12 form one, and the latter has an insertion portion 12i, and it is fitted in the hole 12h who is formed in the end face of the 12ga of first portion.By insertion portion 12i is fitted in the 12h of hole, second portion 12gb just is attachable to the 12ga of first portion.The second helical thread portion 12f that screws with the first helical thread portion 4a of adjusting knob 4 is formed on the second portion 12gb.
To not have the flow control member 12 of attached second portion 12gb to be inserted in the main body 2, and the through hole 2c by main body 2 and 2d be fitted into the insertion portion 12i of second portion 12gb in the 12h of hole, can easily assemble flow dontroller S1 thus.
By manually rotating adjusting knob 4, the first and second helical thread portion 4a and the in axial direction mobile flow control member 12 of 12f.
Be to be noted that projection 12g introduces by through hole 2c and 2d.Utilize this structure, when adjusting knob 4 rotates with respect to main body 2, the edge join of projection 12g and through hole 2c and 2d.Therefore, flow control member 12 does not rotate with respect to main body 2 with adjusting knob 4.Can stop flow control member 12 to rotate by the through hole 2c of main body 2 and the projection 12g of 2d introducing.
